Biotechnological Aspects of the Functional Marmalade Development Using Whey for the Gastrointestinal Diseases Prevention

Abstract

The article reveals the development processes and scientific substantiation of the marmalade of functional use, that is a functional product formulation with biologically active bifidogenic properties contributing to the prevention of the gastrointestinal tract diseases. The research relevance is due to the need to prevent the incidence of a new type of coronavirus COVID-19, that affects many systems of the human body, reduces immunity, while using drug therapy often leads to the natural intestinal microflora violation. To prevent the complications development, it is worth using food products capable of stopping destructive processes in the gastrointestinal mucosa during rehabilitation measures. The researchers developed the cranberry marmalade formulations with the probiotic culture introduction of a different mass fraction: sample 1 with probiotics in a free state, sample 2 with introduced immobilized probiotics; sample 3 with pasteurized whey enriched with a bacterial concentrate containing 0.001 % acidophilus bacillus. The control sample were the recipe of fruit and jelly marmalade. A man obtained a juice concentrate by pressing using an enzyme preparations composition of cellulolytic and pectolytic action. The researchers used the vacuum evaporation method to concentrate the juice to a dry matter content of 52-55 %; prepared the marmalade mass under laboratory conditions using traditional technology with a change in prescription components: probiotic culture introduction at the stage of swollen pectin into the cooled syrup at a temperature below 45 °C. The authors used mathematical modeling of formulations in the technological process to establish the ingredients optimal ratios; identified the rational introduction methods of acidophilus bacillus depending on the organoleptic and rheological product properties after a five-fold measurements repeatability.
